This patch updates the sunxi-ir driver to set the base clock frequency from
devicetree.

This is necessary since there are different ir receivers on the
market, that operate with different frequencies. So this value could be
set if the attached ir receiver needs a different base clock frequency,
than the default 8 MHz.

Like in ddbridge, get rid of all duplicated I2C client handling constructs
and rather make use of the newly added dvb_module_*() helpers. Makes
things more clean and removes the (cosmetic) need for some variables.

The check on a valid ptr on ci->en isn't really needed since the cxd2099
driver will set	it at a	time where it is going to return successfully
from probing.

Instead of keeping duplicated I2C client handling construct, make use of
the newly introduced dvb_module_*() helpers. This not only keeps things
way cleaner and removes the need for duplicated I2C client attach code,
but even allows to get rid of some variables that won't help in making

3 functions that have the same arguments. The code of those
functions is simple enough to just declare them, de-obfuscating
the code.

While here, replace BUG_ON() by WARN_ON() as there's no reason

As warned by smatch:

if s5c73m3_check_status() is called too late, time_is_after_jiffies(end)
will return 0, causing the while to abort before reading status.

The current code will do the wrong thing here, as it will still
check if status != value. The right fix here is to change
the logic to ensure that it will always read the status.

Proper cx2388x chip type is detected in cx25840 probe, the clock
rate is untouched however in probe. The cx25840 only checks for
non default clock values for 888 and provides custom settings for
25MHz 888. This change ensures that cx23888 chips with default 50MHz
crystals will not get configured as if they have 25MHz crystals. A
cx23887 board will continue to be configured for 25MHz crystal as
there is no custom clock support included for it.

The cx25840 driver currently configures 885, 887, and 888 using

driver has passed the cx25840 a non-default clock rate for a
specific chip. If a cx23885 board has left clk_freq at 0, the
clock default values will be used to configure the PLLs.
